Samsung Oven FE Error — Frequency Error Fix

What Does This Error Mean?

Samsung oven FE error means the oven is detecting an incorrect power supply frequency — typically caused by a faulty control board or an unstable power supply. A power reset is the first step; persistent FE usually requires a control board replacement.

Affected Models

Samsung Electric Range
Samsung Slide-In Range
Samsung NE Series
Samsung NX Series

Common Causes

Faulty main control board incorrectly reading power frequency
Unstable or noisy incoming power supply
Power surge damaging the control board's frequency sensor circuit
Incorrect voltage at the outlet (240V supply issue)

How to Fix It

Perform a power reset.

Turn off the oven at the circuit breaker for 5 minutes, then restore power. Some FE errors are caused by a momentary power anomaly and clear permanently after a full reset.
Check the outlet and circuit breaker.

Make sure the oven is plugged into a dedicated 240V outlet and the breaker is fully on (not tripped to middle position). A partially tripped breaker can deliver unstable voltage that triggers FE.
Test with a different outlet if possible.

If you can temporarily connect the range to a different 240V outlet, this helps confirm whether the issue is with the outlet or the oven itself.
Replace the main control board.

If FE returns after every reset and the power supply checks out, the control board's frequency-sensing circuit has failed. Replacement boards cost $100–$250 for Samsung ranges — confirm the part number from your model's label.

When to Call a Professional

If a power reset and outlet check do not clear FE, the control board has likely failed. A technician can confirm this with a board-level diagnosis before ordering an expensive replacement.
